THOMAS ADAMS, OF PIIIE BLUFF, ARKANSAS, ASSIGNOR OF ONE- HALF TO CHARLES H. SEABROOK, OF PINE BLUFF, ARKANSAS.

TWO-WHEEL ENGINE-TRUCK.

To all whom it may concern:

Be it known that I, THOMAS E. ADAMS, a citizen of the United States, residing at Plne Bluff, Arkansas, have invented a certain new and useful Improvement in Two-Wheel EngineTrucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it 'appertains to make and use the same, reference'being had to the accompanying drawings, forming part of this specification, 111 whicht Figure 1 is a plan view of a two-wheel en: gine-truck constructed in accordance with my invention. Fig. 2 is a rear elevation of the truck shown in Fig. 1, and Fig. 3 is an end elevation of the truck shown in Fig. 1.

This invention relates to engine-trucks; and one object of my invention is to provide a cast-metal two-wheel engine-truck that can bemanufactured at asmall cost and 'which will be more rigid and last much longer than the trucks heretofore in use.

In the truck herein shown, which represents the preferred form of my invention, the pedestals are formed integral with the side frames of the truck and the side frames are formed integral with the frame which carries the center-bearing casting, so that a very rigid construction is produced and the cost of manufacturing same is muchlower than the cost of manufacture of the trucks heretofore in use, due to the fact that no assembling of parts or machining or planing down of cooperating surfaces is required. Furthermore, as all of the parts of the truck are formed integral there is no liability of the pedestals or center-bearing frame working oose from the side frames. Preferably .thc pedestals are formed approximately channelshaped, and ribs are provided fer strengthening the side frames and pedestals, the spring-seats being also formed integral with the side frames. i 1

Referring to the drawings which represel'i the preferred form of my invention, 1 desig nates cast-steel side frames, having pedestals 2 of approximately channel shape formed Specification of Letters Patent.

Application filed Apr '7, 1906. Serial No- 310,436-

integral therewith,- the side frames being provided with integral lugs 3, which form 5c truck, as herein shown. Said members are 5 5' provided with removable steel bushings 5, which receive the pins 6, that support the hangers 7, to which the center-bearing cast: ing 8 is connected, so that when the steel bushings become. worn they can be replaced by new ones.

On the upper face of each side. frame is a rib 9, which merges into the adjacent ends of the cross members 4, and ta cred strengthening-ribs 10 are also provirI portions of the side frames, so that a very rigid constructionis insured which will last mueh'longer than the trucks heretofore in use, and which can be manufactured at a much lower cost than said trucks.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. A two-wheel engine-truck comprising side frames having spring-seats and pedestals 7 5 formed integral therewith, and a centerbearing frame formed integral with said side frames; substantially as described.

2. A two-wheel engine-truck comprising side frames having spring-seats and pedestals formed integral therewith, a ccnter-bearing frame formed integral with said side frames, upwardly-extending ribs 10 on the side fran'ics which merge into the end portions of the center-bearing frame, and strengthening-ribs 9 on the side frames whieh merge into the end portions of the center-bearing frame; substantially as described.

.ln testimony whereof I hereunto affix my signature, in the presence of two witnesses,

this 5th day of April, 1906.
